Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of the implementations of embodiments of the invention.
The cleaning of heliostat can adopt the cleaning vehicle, is fixed with the scraper blade device on the cleaning vehicle, and the scraper blade device contacts and inclines into certain angle with heliostat surface, drives the scraper blade under the removal of cleaning vehicle and clears up dust and foreign matter on heliostat surface. Referring to fig. 1, fig. 1 is a view showing a conventional scraper device on a heliostat cleaning vehicle according to the present application, wherein one end of a spring 100 is connected to a connection plate 200, the other end of the spring is fixed to a support rod 300, the support rod 300 is rotatably connected to the connection plate 200, and the other end of the connection plate 200 is fixed to a cleaning scraper 400, i.e. a certain pressure is applied to a mirror surface by the cleaning scraper 400 due to the tension of the spring 100.
It will be appreciated that since the tension of the spring 100 changes with the deformation, the pressure of the cleaning blade 400 against the mirror surface changes, and in the moving process of the cleaning vehicle on the ground, there will be a depression or protrusion on the ground, which results in the cleaning vehicle jolting up and down, such as when the cleaning vehicle encounters a protrusion, when the vehicle body is lifted, the blade device will also be lifted at this time, the inclination angle of the cleaning blade 400 will be reduced correspondingly, the spring 100 will be shortened, the tension of the spring 100 will be reduced, i.e. the pressure of the cleaning blade 400 against the mirror surface will be reduced, some stubborn stains will not be removed well, and the situation of cleaning failure will occur.
If the cleaning vehicle encounters a pothole and the vehicle body is lowered, the scraper device is lowered at this time, the inclination angle of the cleaning scraper 400 is increased correspondingly, the spring 100 is extended, the tension of the spring 100 is increased, that is, the pressure of the cleaning scraper 400 on the mirror surface is increased, and if the change time is rapid, the heliostat is damaged due to the instantaneous stress increase.
The embodiment of the application provides a fixed-force scraper device for solving the problems that the pressure change of the scraper on the surface of the heliostat is large and the heliostat is damaged or cannot be cleaned in place due to the fact that the spring in the scraper device is greatly deformed due to jolt. Referring to fig. 2, fig. 2 is a schematic structural diagram of a fixed-force squeegee apparatus according to an exemplary embodiment of the present application, including: the device comprises a device outer frame 1, a main elastic sleeve group 2 and two side elastic structures 3.
In the embodiment of the present application, referring to fig. 3, fig. 3 is a schematic cross-sectional structure of an apparatus frame according to an exemplary embodiment of the present application, where the apparatus frame 1 is a box structure with an opening at one side, and a main board 11 is on a side of the apparatus frame 1 opposite to the opening; along the direction from the edge of the main plate 11 to the opening, the device outer frame 1 comprises two oppositely arranged side plates 12 and two oppositely arranged cover plates 14; the side plates 12 and the cover plates 14 are connected in pairs and are enclosed into an outer frame inner cavity 13 together with the main plate 11; the main elastic sleeve group 2 and the two side elastic structures 3 are arranged in the inner cavity 13 of the outer frame, and the two side elastic structures 3 are symmetrically arranged on the two side plates 12; the device outer frame 1 may further have other connection structures, such as forming a sealed outer frame cavity 13, or fixing elements are additionally arranged on the main board 11 or the side board 12 to ensure that the device outer frame 1 is structurally stable and can bear a certain pressure, and the specific connection position of the main board 11 and the side board 12 is not limited, and may be connected at the edge positions of the main board 11 and the side board 12, or the edge position of the main board 11 and one side board surface of the side board 12 may be fixed, that is, the side board 12 retains at least the area of the fixing element.
With continued reference to fig. 2, one end of the main elastic sleeve group 2 is fixed on the main board 11, and two side elastic structures 3 are symmetrically arranged on the two side boards 12 respectively; the arrangement of two side elastic structures 3 can provide more balanced acting force for the main elastic sleeve group 2, so that uneven stress is avoided, the scraper 4 is inclined, four, six and other double-number side elastic structures 3 can be arranged in the same way, the stress is balanced for the main elastic sleeve group 2, and the device outer frame 1 can be correspondingly provided with other fixing structures to fix a plurality of side elastic structures 3.
In the present embodiment, with continued reference to fig. 2, the main elastic sleeve group 2 includes: a main elastic member 21 and two rolling connection members 24.
One end of the main elastic piece 21 is fixed with the device outer frame 1, and the other end extends towards the opening direction to be fixedly connected with the scraping plate 4; it will be appreciated that the main elastic member 21 may be a spring, an elastic cord or other elastic member, and is not particularly limited in this application. It will be appreciated that when cleaning the heliostat mirror surface, the blade 4 must exert pressure on the heliostat mirror surface, and the main elastic sleeve set 2 in the embodiment of the present application is used to connect the blade 4 and exert pressure, so the main elastic sleeve set 2 is always in a compressed state in the constant force blade device structure of the present application to ensure that pressure is provided to the blade 4 at all times, not tension. The main elastic set 2 can transmit pressure to the squeegees 4, by which the squeegees 4 clean the heliostat mirrors. The magnitude of the pressure is inversely proportional to the expansion and contraction length of the main elastic member 21, that is, the longer the main elastic member 21 is, the smaller the pressure acting on the squeegee 4 is, the shorter the main elastic member 21 is, and the larger the pressure acting on the squeegee 4 is.
The two rolling connection pieces 24 are respectively arranged on the side walls of the main elastic piece 21 close to the two side elastic structures 3, and the two rolling connection pieces 24 are respectively in rolling contact with the two side elastic structures 3. The rolling connector 24 can reduce the contact area with the two side elastic structures 3, so that the stress is more accurate, and the sizes of the components can be accurately calculated when the later structural size is designed, so that the stress of the scraping plate 4 can be kept constant, and the error is smaller.
Wherein, scraper blade 4 can adopt materials such as rubber, can increase the friction with heliostat mirror surface, realizes better cleaning performance, perhaps at the contact edge with the heliostat mirror surface installation brush, gets rid of surface dust, does not make special restriction to the material and the concrete structure of scraper blade 4 in this application embodiment, can select according to actual need.
In the present embodiment, the side elastic structure 3 includes: side elastic member 31, fixed force plate 32.
One end of the side elastic member 31 is hinged to the side plate 12, and the other end is fixedly connected to the fixed force plate 32. One end of the fixed force plate 32, which is close to the main plate 11, is rotatably connected with the cover plate 14, and one surface of the fixed force plate 32, which is opposite to the side elastic member 31, is in rolling contact with the rolling connecting member 24. By the contact of the fixed force plate 32 and the rolling connecting piece 24, the elastic force transmission on the side elastic structure 3 can be realized, so that the main elastic piece 21 on the main elastic sleeve group 2 can obtain a component force in the vertical direction, and the magnitude of the vertical force can be further adjusted. It is understood that the side elastic member 31 may be a spring, an elastic string, or other elastic member, and is not particularly limited in this application.
In the embodiment of the present application, the contact position between the fixed force plate 32 and the rolling connection member 24 forms a contact point, and the axis of the side elastic member 31 is perpendicular to the axis of the main elastic member 21, and when the main elastic sleeve set 2 works normally, the height of the contact point is lower than the height of the axis of the side elastic member 31.
In order to ensure the stability of the device in this application, the fixed force plate 32 provides a force in the direction of the scraper 4 in most cases by means of the height position adjustment of the contact point. Specifically, the force plate 32 is configured to: when the main elastic sleeve group 2 stretches, acting force towards the direction of the scraping plate 4 is provided for the main elastic sleeve group 2; if the contact point height is still lower than the axis height of the side elastic member 31 while the main elastic sleeve 2 is shortened, the main elastic sleeve 2 is continuously provided with a force toward the blade 4; if the contact point is higher than the axial height of the side elastic member 31, the main elastic bushing 2 is provided with a force directed away from the blade 4.
That is, when the main elastic member 21 is extended, the pressure of the main elastic bushing 2 acting on the blade 4 becomes small, and the two fixed force plates 32 provide forces in the direction of the blade 4, that is, increase the pressure of the main elastic bushing 2 acting on the blade 4, balance the reduced force of the main elastic bushing 2, and keep the pressure on the blade 4 constant. It will be appreciated that the longer the length of extension of the main elastic member 21, the greater the pressure provided by the fixed force plate 32, and conversely, the shorter the length of extension of the main elastic member 21, the less the pressure provided by the side elastic structure 3.
When the main elastic member 21 is shortened, but the height of the contact point is still lower than the axial height of the side elastic member 31, the force-fixing plate 32 still provides a force towards the direction of the scraping plate 4, at this time, the pressure of the main elastic sleeve 2 acting on the scraping plate 4 becomes larger, and the force-fixing plate 32 provides a force towards the direction of the scraping plate 4 gradually decreases, and when the main elastic member 21 is shortened until the height of the contact point is consistent with the height of the side elastic member 31, the force-fixing plate 32 provides a force towards the direction of the scraping plate 4 is 0.
If the main elastic member 21 continues to shorten so that the contact point height becomes higher than the axis height of the side elastic member 31, the pressure of the main elastic bushing 2 acting on the squeegee 4 becomes larger, and the two fixed force plates 32 provide force in the shortening direction, that is, reduce the pressure of the main elastic bushing 2 acting on the squeegee 4, balance the increased force of the main elastic bushing 2, and keep the pressure on the squeegee 4 constant.
From the foregoing, it will be appreciated that a first aspect of the present application provides a constant force squeegee assembly that, in some embodiments, includes an assembly frame 1, a main elastic sleeve 2, and two side elastic structures 3.

The force plate 32 is in contact with the rolling connection 24. The two force plates 32 are configured to: providing a force in the extension direction to the main elastic sleeve 2 when the main elastic member 21 is extended, and continuing to provide a force in the direction of the blade to the main elastic sleeve 2 when the main elastic member 21 is contracted if the contact point height is still lower than the axis height of the side elastic member 31; if the contact point is higher than the axial height of the side elastic member 31, the main elastic bushing 2 is provided with a force directed away from the blade.
When the main elastic sleeve group 2 is jolt to generate larger deformation, the side elastic structure 3 in the scraper device can provide acting force in the same direction as the deformation direction of the main elastic sleeve group 2, namely the main elastic piece 21 is shortened, and when the pressure on the scraper 4 is increased, the same-direction component force provided by the side elastic structure 3 is reduced; the main elastic member 21 is elongated, and when the blade pressure 4 is reduced, the equidirectional component force provided by the side elastic structure 3 is increased; the stress of the scraping plate 4 is constant all the time, so that the situation that the heliostat is damaged due to sudden pressure increase or the heliostat is not cleaned in place due to pressure reduction is avoided.

Through the connection of the connecting pin 3212 and the cover plate 14, the position of the first end 321 of the fixed force plate is unchanged, and when the side elastic piece 31 stretches and contracts, the second end 322 of the fixed force plate can have larger angle change, so that the provided vertical component force has larger change, the change range of the force of the main elastic piece 21 with a larger range can be adapted, and correspondingly, the situation that the road condition is worse can also be adapted.
